I have been trying to make the border of a MapPolygon clickable in QML by the following code:

MapPolygon{
        id: _poly
        border.color: "black"
        border.width: 4
        color: "transparent"
        visible: false
        path: []
        MouseArea{
            id: _polyMousearea
            anchors.fill: _poly.border
            acceptedButtons: Qt.LeftButton
            onClicked: {
                var coord = _map.toCoordinate(Qt.point(flightMapMouseArea.mouseX,flightMapMouseArea.mouseY))
console.log(coord )

                }

            }
        }

    }

I get the following error:

Unable to assign QDeclarativeMapLineProperties to QQuickItem at the line : anchors.fill: _poly.border

Any way to get around this error and make the border clickable?

Thanks

Anchors are used to position QtQuick Item objects relative to another, the border of this element is apparently not an element itself, just a normal grouped property.

Assuming that the path contains a QtQuick Path one option you have is to make the MouseArea fill the whole item, and then use the mouse position in the onClicked handler to check with the path's elements on whether they are hit or not.

  • Thanks!! I have already implemented this but every click has to be checked if the point lies on any sides of the polygon, i wanted to know if there is an easier/efficient way to get around this – saitej Dec 25 '16 at 12:46
